[fedora-arm] not able to mount sata root FS when booting F20 on Wandboard quad

I have a wandboard quad, and would like to mount a sata root FS at boot
time. kwizart helped me to get sata support when booting by doing the
following:
--- instructions from kwizart ---
cat>/etc/modules-load.d/imx.conf<<EOF
# Load ahci imx at boot
ahci_platform
ahci_imx
EOF
dracut -H /boot/initramfs-$(uname -r).img $(uname -r)
mkimage -A arm -O linux -T ramdisk -C none -n $(uname -r) -d
/boot/initramfs-$(uname -r).img /boot/uInitrd-$(uname -r)
--- end instructions ---
I indeed see that sata works at the first login prompt. However, I
cannot mount the rootFS on sata, as apparently the fs mounting is done
before the initialization of the AHCI (sata) subsystem. The following
console output is when booting and mounting the rootFS on uSD card:

------- cut here ---------
mmcblk0p3 has the root file system on uSD card, mounted at [ 4.451255].
Much later, only at [ 8.592222], the sata link is up.
If I try to mount /dev/sda1 for the root fs (in the kernel command
line), I get a panic kernel after a 90 second timeout....
Can someone help me to get ahci initialized before the root fs is mounted?
Cheers, Ronald
